hi, Can haproxy support following backend scenario?
- use HTTP CONNECT to establish a proxy connection - send custom HTTP header with the CONNECT method - then switch to tunnel mode to allow custom TLS protocol through I've not found anything really useful in RFC7231 whether this is a common scenario, and while trying to implement this with haproxy, I either land on: - add headers in `mode http`, but can't handle TLS protocol - use `mode tcp`, but then can't add custom header https://www.rfc-editor.org/rfc/rfc7231#section-4.3.6 ## haproxy.cfg snippet frontend tunnel80_fe bind 10.0.0.1:80 mode http ## strictly speaking the headers aren't part of CONNECT http-request set-header Authorization "Bearer mytoken123" default_backend tunnel80_be backend tunnel80_be mode http server tunnel80 remote.ip:12345 frontend tunnel443_fe bind 10.0.0.1:443 mode tcp ## ignored because we're in tcp mode http-request set-header Authorization "Bearer mytoken123" default_backend tunnel443_be backend tunnel443_be mode tcp server tunnel443 remote.ip:12346 A+ Dave
